Thanks. I'll look at those. I think I might like to go with one that has a fan, so does anyone know of a good heatsink with a fan that cools well and automatically adjusts its RPM by the CPU temperature? Edit: Sorry, I didn't notice the one you suggested had a fan included. I also noticed that it had a fan controller. I have a heatsink now with a fan and fan controller, but it is still pretty noisy and I would like one that adjusts manually based on CPU temps. Thanks.
